Description Field trials with 13 landmark wheat cultivars released between 1965 and 2020 were conducted at 15 different locations during 2019–2020 and 2020–2021, providing data from 30 environments. The study of the historical set of spring wheat varieties from the North-Western Plains Zone (NWPZ) of India developed in the last 55 years demonstrated an improvement of grain yield from 3208 to 6275 kg ha−1 or a genetic gain of 1.21% year−1 over long-term check cultivar C306. In real terms, the yield has increased at a rate of 44.14 kg ha−1 year−1. To compare the present genetic gain study, a trend analysis based on historical grain yield data in standard AVT in the zone from 1980 to 2020 was also attempted, which revealed that the percent yield increase was 0.78 per annum. To achieve a higher rate of genetic gain, it requires greater breeding efficiency in the national breeding program through more systematic use of genetic diversity to introduce novel alleles as well as application of new breeding approaches like speed breeding and genomic selection.
